What are the barriers and facilitators to effective health promotion in urgent and emergency care? A systematic review

Background There are potential health gains such as reducing early deaths, years spent in ill-health and costs to society and the health and care system by encouraging NHS staff to use encounters with patients to help individuals significantly reduce their risk of disease. Emergency department staff and paramedics are in a unique position to engage with a wide range of the population and to use these contacts as opportunities to help people improve their health. The aim of this research was to examine barriers and facilitators to effective health promotion by urgent and emergency care staff. Methods A systematic search of the literature was performed to review and synthesise published evidence relating to barriers and facilitators to effective health promotion by urgent and emergency care staff. Medical and social science databases were searched for articles published between January 2000 and December 2021 and the reference lists of included articles were hand searched. Two reviewers independently screened the studies and assessed risk of bias. Data was extracted using a bespoke form created for the study. Results A total of 19 papers were included in the study. Four themes capture the narratives of the included research papers: 1) should it be part of our job?; 2) staff comfort in broaching the topic; 3) format of health education; 4) competency and training needs. Whilst urgent and emergency care staff view health promotion as part of their job, time restraints and a lack of knowledge and experience are identified as barriers to undertaking health promotion interventions. Staff and patients have different priorities in terms of the health topics they feel should be addressed. Patients reported receiving books and leaflets as well as speaking with a knowledgeable person as their preferred health promotion approach. Staff often stated the need for more training. Conclusions Few studies have investigated the barriers to health promotion interventions in urgent and emergency care settings and there is a lack of evidence about the acceptability of health promotion activity. Additional research is needed to determine whether extending the role of paramedics and emergency nurses to include health promotion interventions will be acceptable to staff and patients.

Background
The NHS is committed to using all staff encounters with patients to help individuals significantly reduce their risk of disease [1,2]. This could reduce early deaths, years spent in ill-health and costs to society and the health and care system. NHS staff have the opportunity to recognise Open Access *Correspondence: behnaz.schofield@uwe.ac.uk appropriate times and situations in which to engage with patients and help them on the pathway to improving their health and wellbeing. Emergency Department and Emergency Medical Services (Ambulance) staff are in a unique position to engage with a wide range of the population and to use these contacts as opportunities to help people improve their health.
The World Health Organisation describes health promotion as a process of enabling people to increase control over, and to improve, their health [3]. Patient education and effective communication can support individuals to make healthy choices [4]. A range of factors may complicate communication in the Emergency Department (ED). These include variable workloads, crowding, uncertainty and time constraints [5]. Some of these factors also apply to the work environment of paramedics. Whilst the nature of urgent and emergency care may offer challenges when considering health promotion activities, it may also be the ideal environment to create opportunities for a 'teachable moment' that will promote subsequent health behaviour change [6]. There is also an economic evidence base for health promotion and disease prevention, as reducing the risk of chronic diseases and injury through interventions aimed at modifying lifestyle risk factors is known to be cost-effective, and could reduce health inequalities [7].
Given the potential health gains, research should be encouraged to organise and deliver effective health promotion interventions in urgent and emergency care settings. The aim of this systematic review was to examine barriers and facilitators to effective health promotion by urgent and emergency care staff. This paper reports on an evidence synthesis relating to the barriers and facilitators to effective health promotion interventions in urgent and emergency care settings. The paper will inform the direction of future research in this field by providing a basis to further explore areas of interest and expressed needs.

Study design
The search methodology and reported findings comply with the relevant sections of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement [8]. Prior to performing this review, a protocol was developed and registered with PROS-PERO (registration number CRD42020205180). The research question guiding this systematic review was as follows: "What are the barriers and facilitators to effective health promotion interventions in urgent and emergency care settings?" Consensus was reached among all reviewers on search syntax, inclusion and exclusion criteria, and the criteria for assessment of validity and relevance in the identified articles.

Eligibility criteria
Our eligibility criteria followed the Participant, Exposure, Outcome and Study design (PEOS) framework [9]. We only included papers written with publication dates limited from January 2000 to August 2020 in all our information sources. Limiting the search period to 2000 onwards sought to identify all relevant research published in a contemporary timeframe.

Search strategy
The search strategy was informed by an initial overview of literature in the field and the assistance of a subject librarian. The following bibliographic databases were searched: CINAHL, MEDLINE, Cochrane Central, Cochrane sensitive RCT search strategy, Scopus and Psy-cINFO on 18th August 2020. The search was repeated on 14th December 2021 to capture any relevant papers published since the original search date. The search included title, abstract, keywords and subject headings to describe the population (paramedics, doctors, nurses and support staff in emergency departments) and the setting (prehospital emergency medical (ambulance) services and hospital emergency departments). A detailed strategy for MEDLINE is given in (Table 1) and was adapted to the other databases. All articles that met the search terms were exported from the search engines to the Covidence systematic review management system [10]. Backward chaining within the final sample was reviewed for potentially relevant papers.

Selection of studies
A range of research methods was considered including randomised controlled trials, observational studies, Table 1 detailed search strategy MEDLINE, CINAHL, Cochrane Central, Cochrane sensitive RCT strategy, Scopus and PsychInfo databases were searched using the following search terms: 1. promot* or educat* or program* or prevent* or project* or intervent* or strateg* 2. "health education" or "patient education" or "primary prevention" or "health promotion" or "primary health care" or "preventative health care" 3. paramedic* or prehospital or pre-hospital or "emergency care" or "emergency department" or "accident and emergency" or ambulance or "Minor Injury Unit*" or "Urgent Treatment Centre*" 4. S1 N2 S2 N2 S3 surveys and qualitative research. Any literature (quantitative, qualitative or mixed methods) that reported on the facilitators or barriers to health promotion in urgent and emergency care settings was considered for inclusion. This included research papers of any kind but not systematic reviews, literature reviews, editorials, commentaries or letters. Unpublished data was not included.
Based on the inclusion criteria (Table 2), two reviewers (BS and UR) independently screened the titles and abstracts of eligible articles to eliminate articles not meeting the inclusion criteria. Articles not meeting the inclusion criteria based on the title and abstract were excluded at this point. The full text of the agreed included articles was screened independently by the same two reviewers (BS and UR). Articles were excluded at the full-text stage if they did not directly meet the eligibility criteria on closer inspection of the full article. Additionally, references in review articles were screened using the same criteria. Any conflicts during the screening process were resolved through discussion by the two reviewers with reference to the inclusion and exclusion criteria.
Due to heterogeneity between study settings, designs and screening tools used, the included studies have been described narratively [11].

Data extraction and quality assessment
A bespoke data extraction form was designed in consultation with the review team and piloted on two papers identified during the scoping search. No changes to the data extraction form were recommended following the pilot phase. The data extraction form is reproduced in Additional file 1 Appendix 1. Two authors extracted data separately from the eligible studies (BS and UR). The reviewers conferred and agreed on studies to be included.
The Mixed Methods Appraisal Tool (MMAT) was used to assess the studies for risk of bias, relevance, trustworthiness and results [12]. The authors of the MMAT encourage the provision of a detailed presentation of the ratings of the five criteria within the tool to reflect the quality of the included studies. In this review the studies were ranked as high (all criteria met), medium (four out of five criteria met) and low (three or less criteria met). Much of the MMAT assessment process focuses on the risk of bias in the study under consideration, and therefore studies judged as low quality are at the highest risk of bias when this tool is applied. Conflicts in risk of bias assessment were resolved through discussion by the two reviewers and with reference to the appraisal tool. The methodological quality of each study was independently analysed by two authors (BS and UR). No studies were excluded based on quality assessment. The quality rankings for each study are presented in Table 3.

Study selection
Overall, research into barriers and facilitators of health promotion activity in urgent and emergency care settings was found to be limited. No relevant research was identified regarding paramedics. It was therefore necessary to increase the scope of the review to include community paramedicine programmes in rural settings in North America and Australia. Whilst these programmes are not directly transferable to the role of paramedics more generally, they are able to demonstrate the acceptability of this non-traditional role, which includes health promotion, amongst the wider paramedic profession.
154 papers were identified through database searching. Following the removal of duplicates, 108 records were reviewed by title and abstract. Of these, 63 were removed. 45 records were assessed for eligibility based on a full text review. 26 were excluded, with 19 records being included in the review. Inter-rater agreement for

Intervention
Any intervention or combination of interventions delivered by urgent and emergency care staff for the promotion of health. The person delivering the intervention and the setting of the intervention was noted.

Exposure
Any health promotion activity.

Outcome
Any barriers or facilitators to undertaking health promotion interventions, including but not limited to engagement with the activity and perceived time constraints, and secondly, how patients and staff view delivery of the interventions in urgent and emergency care settings.

Setting
Pre-hospital setting which is usually the home or normal place of residence of the participant, in a public place or in the ambulance. Emergency Department of a hospital. Minor Injury Unit or similar facility.     Studies took place in the following countries: 11 in the US [13,14,16,18,20,22,23,[25][26][27][28], 1 in Jordan [30], 2 in the UK [17,24], 4 in Australia [15,19,21,31] and 1 in Canada [29]. The characteristics of the included studies and participants are described in Table 3.

Data synthesis
The 19 studies were published between 2000 and 2020 and included a range of populations and research methodologies. Ten studies were surveys, four were randomised controlled trials, two were retrospective reviews of records and three were qualitative interviews/focus groups. Sample sizes ranged from 2149 to 11 participants. Four themes capture the narratives of the included research papers: 1) should it be part of our job?; 2) risk of offending patients; 3) format of health education; 4) competency and training needs. These four themes capture the reported barriers and facilitators to effective health promotion interventions in urgent and emergency care settings.

Should it be part of our job?
In general staff support health promotion taking place in the ED. [17,18,21,24,26,28] Paramedics in rural communities and emergency services technician firefighters also see health promotion as an acceptable part of their jobs [20,27,29]. However, ED nurses in one Jordanian study felt it was not part of their role [30].
Whilst nurses felt that health promotion was part of their role, they reported providing health promoting advice less than half the time when these interactions would have been indicated. They reported lack of time and a lack of support systems for patient follow up as barriers [18]. Although ED doctors reported feeling responsible for promoting the health of their patients, only a minority reported routinely screening and counselling their patients with identified modifiable risk factors. Most reported not feeling confident in their ability to help patients change their behaviour [26]. In one study doctors reportedly offered health promotion intervention more often than nurses. Time constraints and a lack of health promotion infrastructure in the ED were cited as challenges to intervention delivery [17]. Patients and carers attended to by community paramedics accepted paramedics in a non-traditional preventative healthcare role [29].

Staff comfort in broaching the topic
The health conditions of interest to ED patients in one study were stress and depression and among the health topics, participants were most interested in exercise and nutrition [22]. Smoking is the health topic most commonly discussed according to ED doctors in one study [26]. Whilst ED staff in another study stated that drug and alcohol misuse were the most appropriate risk factors to discuss in ED and that the interventions in the ED were most appropriate when risk factors were directly related to the ED presentation [17]. Paramedics had success with injury prevention advice as part of their role in community paramedicine [27]. The recording of health risks and counselling was noted in only 22% of nonacute patients with one or more modifiable risk factors; with doctors documenting more health risks than nurses [28].
Whilst 20% of all calls for an ambulance service involve alcohol, not many ambulance officers ask the patients they attend about quantity and frequency of alcohol use [21].

Format of health education
Educational, and to a lesser extent behavioural change, approaches are the main forms of health promotion described in the urgent and emergency care setting [32]. Patients and visitors stated they preferred traditional forms of books and leaflets to support the information they were given on health-related topics [22]. An educational video used during ED waiting was shown to improve knowledge and act as an acceptable low-cost teaching tool for focused patient education that may allow clinicians to use patient waiting time for health promotion [16,25]. The use of learning style-tailored information led to patients perceiving improved knowledge [14]. Using a structured education tool improved nurse confidence in undertaking personalised education prior to discharge from the ED. [19] A computer kiosk to promote child safety in a randomised controlled trial in an urban paediatric emergency department demonstrated the applicability of computer technology for education in a busy ED. [13] Inadequate patient education has been cited as a potential cause of re-attendance of asthma patients to the ED. A randomised study aimed to compare the effectiveness of patient-centred education (PCE) and standard asthma patient education on ED re-attendance. PCE patients had fewer re-attendances at 4 and 12 months. A learnercentred approach to education may be useful in reducing re-attendances to the emergency department [15]. Internet referrals may provide a potential solution to limited staff time in emergency departments for health education [23].

Competency and training needs
There was a statement of continued need for education in health promotion roles in those studies where staff views were collected [19,21,24,26,30,31]. Nurses felt they lacked competency [30], were less knowledgeable on some health topics than others [24,26,31], and requested a structured approach [16]. Paramedics requested specific training to deal with patients affected by excessive alcohol intake [21]. Staff were concerned that existing health promotion interventions were not systematic and had not been evaluated and risked becoming a marginalised part of their work [31]. Lack of health promotion knowledge, lack of time and not wanting to extend a patient's stay in the ED were reported as barriers.

Discussion
Nineteen studies with varying designs were identified as relevant for our exploration of barriers and facilitators to effective health promotion in urgent and emergency care. The evidence base is not well developed. There is limited evidence describing the barriers to health promotion activities in EDs, and facilitators are particularly poorly captured. Two literature reviews suggest that educational interventions in the ED are both possible and feasible, while indicating that additional research is needed to provide a more substantial evidence base from which to identify effective approaches designed specifically for this healthcare setting [33,34]. This review supports these statements and highlights a need for further research in this area, in particular to understand the views of staff and patients on the potential for an expansion of the role of ED nurses and paramedics.
Almost all relevant research has suggested that urgent and emergency care staff view health promotion as a part of their job, however time restraints and a lack of knowledge and experience are identified as barriers to undertaking health promotion interventions. If emergency nurses feel more confident in their educating practices, and are supported by a structured format, patients may benefit from better quality patient education provided in the ED. The provision of a health promotion infrastructure in the ED will be a positive step towards providing a standard approach and is likely to include training and support pathways for ED staff to ensure that health promotion is an integral part of their role.
Whilst patients have reported that the health promotion topics they are most interested in are exercise and nutrition, ED staff shy away from health promotion interventions relating to weight management, diet and exercise [18,22,26] There may be worries around seeming insensitive to patients and further stigmatising patients that prevent staff from engaging in these interactions. Staff in general report providing health promotion interventions on blood pressure management, smoking and alcohol use. ED staff agree that health promotion interventions are most effective if related to an acute ED presentation. This may be one reason why diet and weight management are not seen as appropriate interventions in this setting. A study of General Practitioners and practice nurses in the UK on talking to primary care patients about weight found that staff had concerns about raising the issue of overweight; the most common being that patients would react emotionally to the message [35].
Patients reported receiving books and leaflets as well as speaking with a knowledgeable person as their preferred health promotion approach. A systematic review of the effectiveness of traditional media (leaflet and poster) to promote health in a community setting, demonstrated that traditional health promotion media such as leaflets and posters are still useful in the current digital era, especially for adult respondents [36].
A number of studies have demonstrated the feasibility of video and internet use in the ED waiting areas as acceptable methods of patient education. A diseasespecific educational video may be a relatively low-cost tool for focused patient education in the ED waiting room. These combined approaches may have the potential to offer improved outcomes for patients visiting the ED but adopting them will require structural and cultural changes. A systematic review of the effectiveness of video-based education in modifying health behaviours demonstrated that for certain health messages and conditions video interventions appear to be effective [37].
Patient discharge from the ED appears to be an effective time to maximise engagement with ED recommendations and improve self-care according to the literature reviewed. A variety of potential teaching methods and teaching materials have been used in the ED; however, it is still unclear which of these are most effective, and for which subgroup of the population [38]. Given the potential for health gains, research should examine how to organise and deliver the most effective patient education in the ED.
The role of the paramedic in health promotion is beginning to receive some attention [39,40]. Health promotion and healthy lifestyle interventions are outlined in the Paramedic Specialist in Primary and Urgent Care Core Capabilities Framework produced by the College of Paramedics [41]. The included literature demonstrates support from community paramedics and emergency medical technicians in Canada, US and Australia for the expanded role of health promotion as part of their activities when treating patients in the community [20,21,27,29]. This literature highlights how paramedics in the ambulance service may be able to adapt to health promotion activities when treating and discharging patients at home.
The themes identified in this review can be both facilitators and barriers to undertaking effective health promotion interventions in urgent and emergency care settings. If staff view health promotion as part of their role it will be a facilitator to undertaking effective health promotion interventions in urgent and emergency care settings. Conversely, if staff feel there is a tension between their role as urgent and emergency care practitioners and health promotion, it is likely to act as a barrier with restraints on time and lack of confidence having an impact on the likelihood of staff engagement with health promotion interventions in these settings. On the theme of staff comfort of broaching the topic, if staff view the health promotion discussion as sensitive, it will act as a barrier, and they are less likely to engage in the conversation. Conversely, if staff feel comfortable with the health promotion topic it will act as a facilitator, and they are likely to engage with the patient more readily. Additionally, if the format of the health education approach is patient-centred, and appropriate for their learning needs, it is likely to act as a facilitator to undertaking effective health promotion interventions in urgent and emergency care settings. Conversely, inappropriate health education approaches could act as a barrier in these settings. Finally, if staff feel they lack competency and training in health promotion it is likely to act as a barrier to undertaking effective health promotion interventions in urgent and emergency care settings. Conversely, staff who feel they have adequate competency and training will be more likely to undertake effective health promotion interventions.
Heterogeneity in study settings, designs and the screening tools used in the included studies affects the conclusions and recommendations of this systematic review as it decreases the generalisability of the findings to the management of health promotion interventions in the urgent and emergency care settings [42,43]. This variability in participants and methodological diversity is the reason we decided to describe the included studies narratively, rather than attempting any form of statistical analysis.
The lack of evidence on the acceptability of health promotion for patients and service providers in urgent and emergency care settings, coupled with an imperative to ensure staff talk to the public they are treating about their health and wellbeing across all health and social care organisations, requires further exploration. There is a need to efficiently integrate existing information and determine the extent to which findings are generalisable across health care settings. This will guide future research on health promotion in urgent and emergency care to generate evidence on patient benefit. This review draws together a disparate literature to identify themes and create an overview with pointers towards future research that has the potential to change practice.

Limitations
This review was limited to research papers published since January 2000. There is a risk of missing grey literature and relevant literature published prior to 2000. The wide range of methods, countries and interventions described in the included studies makes generalisation difficult.

Future directions
Future research is necessary to define and understand the barriers and facilitators to health promotion interventions in urgent and emergency care settings. Current evidence does not support changes to clinical practice, and further research is required to build an evidence base that will justify the introduction of new interventions and staff behaviours when caring for patients in emergency care. We anticipate existing clinical practice will be modified if high quality research demonstrating the clinical and cost effectiveness of one or more defined interventions relevant to a particular health system is published.

Conclusions
Few studies have investigated the barriers to health promotion interventions in urgent and emergency care settings. The papers reviewed in this article demonstrate a willingness amongst staff in urgent and emergency care to undertake health promotion activities. The studies included highlight what emergency department nurses may need to undertake the role of health promotion in their clinical setting. The included papers are mainly from the US, Canada and Australia and there are cultural considerations that need to be considered in future research. Additional research is needed to determine whether extending the role of paramedics and emergency nurses to include health promotion interventions will be acceptable to staff and patients, and to generate an emerging evidence base that will direct future research and practice.
